I wanted to provide some of the historic evidence of UFO's and aliens on record. I'll start off with some of the latest to the oldest.
UFO Coin, 1680
French Medal
commemorating a
wheel like object
UFO sighting
The Madonna with Saint Giovannino - above Mary's left shoulder is a shining, or glowing, disk shaped object. A man and his dog can clearly be seen looking up, perhaps in wonder, at the floating object in the composite below. Painted in the 15th century, Palazzo Vecchio lists the artist as unknown; although it is attributed to the Lippi school.
Upon closer inspection, the man seems to be looking away from the UFO, behind him and over his shoulder. Or, more likely, the notably out of place object may be imagined floating above the ground between them. From either perspective, could Mary be seen as blocking the two babies from the flying saucer or man's view? The dog certainly glimpses the hovering object - with it's mouth open, could even be said to be barking at it. But what is that dark, sparkling, disassembled figure beside them - a demon, a dwarf, or an ethereal being?
A clear body, legs, head and tail can be made out. Could this represent a type of alien, known to the artist? Also, Mary's halo seems a bit shadowy: more like a vaporous disc than a ring of light - darker inside, smoky.
The Baptism of Christ
Fitzwilliam Musuem, Cambridge, England
Painted in 1710 by Flemish artist Aert De Gelder
depicts a classic, hovering, silvery, saucer shaped UFO
shining beams of light down on John the Baptist and Jesus.
What could have inspired the artist
to combine these two subjects?
15th Century Tapestries - French Basillica Notre-Dame in Beaune, Burgandy.
Both depicting the life of Mary, hat shaped objects can clearly be seen in the sky.
The above is entitled "The Magnificat" - the below tapestry's title is unknown.
These images from the 12th century manuscript "Annales Laurissenses"
(Latin for "volumes" or "books" about "historical and religious" events)
depicts the Saxon siege of Sigiburg Castle, France, in the year 776.
The Crusaders had the medieval French completely surrounded
when the "flaming shields" suddenly appeared in the sky;
(the manuscript reports this as being over a church).
Assuming the French were being protected,
the Saxons fled in fear from the UFOs.

Ancient Evidence
This highly odd figure which seems to be wearing a suit was found in Kiev and is apparently dated at around 4,000 BC.

The Lolladoff plate, discovered in Nepal, appears to depict a humanoid being resembling a "grey", and a UFO type object at the center. Dated 7,000 BC.

[note: LOL, look at that little alien there on the disk! Hilarious]
Because these figures are made of gold, they are hard to date, but it's certain that they are least 1000 years. Estimations place them between 500 and 800 CE. They were found around Central America and coastal areas of South America. For anyone who knows anything about aeronautics these items are simply mind blowing. They depict undoubtable knowledge of aeronautics. In the last picture you see scaled up models of these figures, three German model enthusiasts, Eenboom, Belting and Lübbers, have constructed a propeller-driven and jet-engine driven scale models of these figures, and they flew beautifully, compare them with
these model RC jets. The source for these pics is the Ancient Aliens series 2010.
This drawing depicts a UFO sighting over Hamburg,
Germany on the 4th November 1697. These mysterious objects were described as "two glowing wheels".

This picture by Samuel Cocciu depicts large black and white spherical UFO's over Basel, Switzerland in 1566. Notice the reaction of the people.

An illustration from a book titled "Ume No Chiri (Dust of Apricot)" published in 1803. A "foreign ship and crew" witnessed at Haratonohama, Japan this strange object, said to be made of iron with weird letters inside the ship - shown in the drawing.

This peculiar illustration showing a spherical type UFO in the sky, comes from the french book "Le Livre Des Bonnes Moeurs" by Jacques Legrand, dated 1338.

This tapestry is titled "Summer's Triumph", created in Bruges, 1538, located at the Bayerisches National Museum. Here we see odd saucer/disk type UFO's in the sky above the horizon.

This Crucifixion piece is located in the Svetitskhoveli Cathedral of Mtskheta, Georgia, on one side of the grave of Sidonia. Other variations of the crucifixion done in byzantine style show these objects as the Sun and the Moon.

This 14th century painting is located in the Visoki Decani Monastery in Kosovo. The two objects on either side seem to depict flying crafts of some description, with people inside them.

crucifixion art
I did a loan signing for someone from Rainbow City Alabama at the San Francisco Hyatt a few days ago. He told me his city got its name from a plentiful array of gorgeous rainbows. This got me to thinking about where I've been living the past 16 years. San Francisco has it's own kind of rainbows, that's for sure. The rainbow flags of the gay Castro district!
Then there's the other issue that San Francisco has no cemeteries. It's quite an eye opener to someone like myself who rarely leaves the city to take a little trip now and then. I'm always amazed at all the burial grounds other cities have. Following the 1906 earthquake and fire, many San Franciscans simply disappeared into the ether.
I've since come to the realization that the reason San Francisco has no acknowledged murders as stated on its crime stopper site or cemeteries as such, is possibly because it has coined itself the City of Dreams. This is a city where if you can dream it with all your heart, it becomes reality. Such the popularized phrase from the Tony Bennett song, I Left My Heart in San Francisco will never die. 
Therefore, San Francisco's not a city of destruction or death as past history has always demonstrated, but rather has overcome all odds by being a city of dreamers. Such is why San Francisco is so unique. So many have suffered and died in this city from various disasters yet it has built itself time and time again on people's hard work based on their dreams.
